Although other countries are finding non-traditional oil reserves and establishing methods of extraction to retrieve them, who is still the king in proven oil reserves?

I think the correct answer would be Saudi Arabia. Though, a lot of countries are trying to find for alternative oil reserves and research on different extraction methods it is still the said country who supply a large amount of oil in many countries. Hope this helps.
